چکیده

In this paper the spectral properties of two different types of projection signals appearing in 3-D tomography are considered. In particular, the spectral behaviour of the 3-D projection signal generated via a plane integral is analysed and its effective support region is figured out. On the basis of this result, an optimal interleaved sampling pattern is established. Compared to the traditional progressive sampling method, a reduction of sampling points by the factor 4 is achieved. Copyright © 2005 IFAC

Synthesis, Spectral Characterization and DFT Calculations of New Co(II) Complexes Derived from Benzimidazoles

The synthesis, characterization and quantum-chemical investigations of two new Co(II) complexesderived from fluorescent benzimidazoles have been reported. Two new fluorescentheterocyclic ligands were synthesized from the reduction of imidazo[4',5':3,4]benzo[1,2-c]isoxazole derivatives, and characterized by elemental analyses, IR, mass, and NMR spectra. Coordination of the bidentate ligands ...

Convergence Analysis and Preliminary Experimental Feasibility for MRI-Localized Region Spectroscopy with NIR Diffuse Optical Tomography

NIR tomography image reconstruction can be improved by incorporating spectral constraints and prior spatial information. The convergence of scattering power was studied based on the distribution of projection error with different parameters. The reason that scattering properties are harder to recover than chromophore concentrations was discussed. Using “hard prior” spectral reconstruction, the ...

Utilization of an optimum low-pass filter during filtered back-projection in the reconstruction of single photon emission computed tomography images of small structures

Introduction:Low-pass filters eliminate noise, and accordingly improve the quality of filtered back-projection (FBP) in the reconstruction of single photon emission computed tomography (SPECT) images. This study aimed at selection of an optimum low-pass filter for FBP reconstruction of SPECT images of small structures. Material and Methods:Sp...

Spectral rhoZ-projection method for characterization of body fluids in computed tomography: ex vivo experiments.

RATIONALE AND OBJECTIVES The identification of body fluids in computed tomography poses a major diagnostic challenge. The chemical composition of body fluids deviates only slightly from water with very similar computed tomographic (CT) values, which typically range from 0 to 100 HU. The aim of this study was to assess physical and chemical properties of different body fluids in an ex vivo setti...
